Sorkin Movies:
The Social Network - Pretty accurate. As is normal with Sorkin, there was some artistic license (Winklevosses and Saverin were never in the same deposition, for example), but a lot of the details, like Zuckerberg writing Facesmash while drunk and blogging was accurate. I suspect people's opinion on Sean Parker is entirely based on perspective, so I don't know that there is a factual answer on that. Also, Zuckerberg got thumped in both lawsuits, and the movie shows that he probably deserved it.
Steve Jobs - I read the book. The movie uses this completely artificial construct of 3 product debuts to have a ton of dialogue and action, so the details are way off. For example, by the third act, Wozniak had been gone from Apple for a decade, yet Jobs tells Wozniak that he can keep his job. Jobs' friends claimed the movie was inaccurate and overly negative. That said, in an interview, Wozniak said that the movie is an accurate portrayal of his relationship with Jobs, as did most of the anti-Jobs people. Given that Lisa Brennan Jobs recently came out with a book that was absolutely brutal on her father, it appears that Sorkin may have even pulled some punches when it came to that relationships.
Charlie Wilson's War - Pretty accurate. The complaints about the movie were primary that other people did not get more credit for Afghanistan. The movie was about Charlie Wilson. People need to chill.
Moneyball - this movie gets some weird facts wrong. For example, a lot of the drama revolves around Scott Hatteberg and whether Howe would play him or not. Hatteberg had a solid season and played a lot. I don't think there was really that much drama about playing him. Some of the best players, like Miguel Tejada and Eric Chavez, don't even make an appearance.
